I could help you script just tell me what they say and i should be able to make it (unless its beyond my scripting lvl and ill notify you if its to complex) plus if you can upload your rom to here
and tell me the link it gives you so I can apply the scripts and test them.
are you using advancemap? if you are here is an example of a warp
pallet town(3.0)in the map the warp no is, say 2
warp bank=3
warp map=0
warp no=2
or you can just send me the rom somehow and i can fix it up.
